Are you aware of the emulsifiers in the foods you eat?

Look at some of the foods you buy at the store. For example, things like mayonnaise, ice cream, chocolate, peanut butter. How smooth and uniform are they? They can be stored for a long time. Have you ever wondered how they are made like this? One of the secret ingredients behind this is called "emulsifiers." Today we are going to talk about what these emulsifiers that are always on our plates are and whether they are good or bad for our body.

So, what are these emulsifiers?

Simply put, emulsifiers are substances that bind two things together that don't want to mix, like friends, and mix them together. The best example is oil and water. No matter how much you shake a bottle at home with a little water and a little coconut oil, after a while the oil will come back to the top and separate, right? Emulsifiers are chemicals that force two liquids that don't mix together and help keep the mixture stable.

These are added to many of the processed and packaged foods we eat.

• Mayonnaise: Mix oil and vinegar (water-based) together.
• Ice cream: Reduces the formation of ice cubes and gives a smooth, creamy texture.
• Chocolate: Keep the cocoa butter and cocoa powder separate.
• Bread and bakery products: Increase shelf life and reduce dryness.
• Sauces and salad dressings: Keep the oil and other liquid components at the same thickness, without separating.

These are added to foods to improve their appearance, give them a smooth texture, and increase their shelf life. While some emulsifiers are made from plants (e.g., soy), most are made from animal products, and most are synthetically produced in laboratories.

Not only in food, but also in the skin care products, creams, and medications we use, these emulsifiers are used to help keep oil- and water-based ingredients mixed together.

How do these things work? Let's look at it a little scientifically.

This is very easy to understand. Think of an emulsifier molecule as a small magnet, but with two sides that work in two ways.

1. One side loves water: We call this hydrophilic. This side is attracted to water molecules.

2. The other side likes oil: This is called hydrophobic. This side is attracted to oil molecules.

Now imagine that we add an emulsifier to a mixture of oil and water. What happens is that the emulsifier molecules go and gather around the little oil droplets. Their oil-loving sides turn towards the oil droplet and hold it tightly. At the same time, their water-loving sides turn outward and make friends with the surrounding water molecules.

This way, even though the oil droplets are floating in the water, they are not allowed to clump together to form a large oil layer. This is why we get a smooth, stable mixture. Milk is a good example of a naturally occurring emulsion. Margarine is the opposite , a mixture of water droplets in oil.

Main types of emulsifiers found in food and skin care products

There are various types of emulsifiers in the foods and creams we eat. It's good to know about some of these.

The most important question: Are emulsifiers really bad for the body?

This is the most important thing we all need to know. Recent research has shown some risks in this regard.

Impact on gut health

Our intestines are not just a tube through which food passes. They are home to trillions of microorganisms (good bacteria) that are essential to our health. We call this the gut microbiota . These good bacteria help us digest food, make vitamins, and strengthen our immune system.

A 2021 study found that two types of artificial emulsifiers, specifically carboxymethylcellulose (CMC) and polysorbate 80 , harm the good bacteria in the gut and increase the risk of intestinal inflammation .

These chronic inflammatory conditions can lead to inflammatory bowel diseases (IBD), such as Crohn's disease and ulcerative colitis . Other studies also suggest that they may have an impact on conditions such as obesity, Type 2 Diabetes Mellitus, and heart disease.

Effect on the skin

Emulsifiers in some skin care products, especially those containing sulfates, such as SLS, can cause dryness, irritation, and damage the skin's natural protective layer. They can also cause allergic reactions in people with sensitive skin.

So what do we do? How can we protect ourselves from these?

Hearing all this can be a little scary. But there's nothing to worry about. The main thing is to be aware of the food and products we buy.

1. Read the labels: When you buy something at the store, make it a habit to read the ingredients list. Check for the artificial emulsifiers mentioned above.

2. Reduce processed foods: Reduce your intake of packaged, heavily processed foods as much as possible. Instead, eat more natural foods like fresh vegetables, fruits, and whole grains . If you prepare your meals at home, you have complete control over what you eat.

3. Be careful with skin care products: If you have sensitive skin, choose products that are labeled "sulfate-free." Before using a new product, do a patch test to see if you have an allergic reaction.

Research on this is still ongoing, so the best course of action for now is to limit your consumption of processed foods containing artificial emulsifiers as much as possible.
